UN Projects 11% Emissions Rise by 2030, UK Hydrogen Blending Aims for 2.5 Million Car‑Equivalent Cuts

The United Nations Emissions Gap Report 2023 projects that, without stronger policies, annual greenhouse‑gas output will increase 11% by 2030 instead of the 45% reduction required to stay on a 1.5°C pathway. The report notes that current national pledges fall short of the interim target, putting the 2050 net‑zero goal at risk. The International Energy Agency warns that an inflection point in clean‑energy investment is needed to reverse the trend.

- Global emissions are set to increase 11% by 2030, contrary to the 45% cut needed for the 1.5°C target (UN Emissions Gap Report 2023). - Blending 20% hydrogen into the UK gas grid would lower annual carbon emissions by an amount equivalent to removing 2.5 million cars from the road (Energy Networks Association). - The HyNet project will store 35,000 tons of hydrogen in repurposed salt caverns to balance supply and demand fluctuations (HyNet Northwest documentation).

The 11% rise signals that existing climate policies are insufficient to curb warming, raising the likelihood of exceeding 1.5°C within the next decade. Hydrogen blending offers a near‑term lever: substituting a fraction of natural gas with hydrogen cuts CO2 without requiring appliance changes, and the stored 35,000‑ton buffer helps manage intermittent renewable output. Success depends on scaling electrolysis powered by renewables and building the necessary pipeline and storage infrastructure.
